Emotie is an addon which adds the classic slash command emotes from other games, such as World of Warcraft, to WildStar. Once you install the addon, using any of these slash commands will make your character preform classic emotes, adjusted to your character's sex and target (or lack there of).
Thus, every emote on this page should be included: http://www.wowwiki.com/List_of_emotes as well as many others!
Please note any errors you find and I will quickly fix them.
Future versions of Emotie will add any other requested emotes and physical actions for them as well (such as waving when you use /welcome).
